THOMAS E. JORDAN, or SOUTH L-AMBETH, ENGLAND, A-SSIGNOR TO B. H. BARTQL, OFPHILADELPHIA, PENNSYLVANIA.

Letters Patent No. 83,505, dated October 27, 1868 patented "in Englmtd, October 28, 1865s IMPROVENIEN'I IN STEAM-GENERATORS.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it my concerns 7 Be it known that I, THOMAS B. JORDAN, of South Lambeth, London, England, have invented certain Improvements in Steam-Boilers, for which Ldtters Patentof the Kingdom of Great Britain and Ireland were granted to me on the 28th day of October, A.

D. 1865; and I do hereby declare the following to be a full, clear, and exact description of the same.

My invention consists-- First, in the novel construction of a steam-boiler, the main body of which consists of vertical or inclined wrought-iron tubes. I

Second, in a novel arrangement of the boiler with respect to the brick-work, with the view of obtaining a uniform distribution of heat to the vertical or iiichned tubes. i

In order to enable others skilled in the art to make and apply my invention, I-will now proceed to describe its construction and operation,referencebeing had to the accompanying drawing, which forms a part of this specification, and in which- Figure 1 is a vertical section of my improved steamboiler, and

.Figure 2 a sectional plan of the same.

The body of the boiler'consists of any desired number of wrought-iron tubes, A, arranged'in rows as seen in fig. 2. In the present instance these tubes are vertical, but if desired they may be inclined, and there. are three rows, two containing three tubes, and an intermediate row of four tubes, but this arrangement may be modified in accordance with the size of the boiler.

The tubes of each row are so secured at their lower ends to a horizontal pipe, B,-that there is a free -communication between the latter and the said tubes A, which fit in sockets, co, the latter being fitted to flanges, b, on the horizontal pipes, and the whole beingsecured firmly'together by bolts D, one bolt passing through each tube, the lower bent end or- T-shaped head of the bolt bearing against the inside of the horizontal pipe, at a point adapted to receive it, and its upper end passing through a cap, d, fitted to the top of each vertical or inclined tube,'above which cap the bolt is furnished with a suitable washer and lint.

At the upper end of the generator is a horizontal pip'e, E, which may be termed the general steam-receiver and, distributer, inasmuch as it is made to communicate withthe tu es'A, at the upper end of the same, through a series of small tubes e, in a manner which will be-readily understood. This pipe E is furnished with a suitable safety-valve and with a shut-oh" valvethrough which steam is admitted to the engine.

The feeding ofthe boiler is effected through a tube, F, and the blowing off through a tube, E,'Which tubes communicate with the horizontal pipes B B, in a manner' readily understood by reference to the drawing.

Hitherto I have referred to the peculiar construc- .tion of the generator only. I will now proceed to describe another important feature of my invention, which is the arrangement of the boiler on the foundation.

It will be observed, on reference to fig. 1, that the horizontal pipes B and the sockets a, in which the vertical or inclined tubes A fit,'are embeddedin the brick-work foundation G, and are consequently protected from the direct action of the products of combustion of the fuelon the grate H of the fire-place I, to which action, however, the vertical orinclined tubes A are directly exposed, these tubes being contained in a rectangular chamber of brick-work, and this chamber terminating above at f,where the brick-work meets the caps d at the upper" end of the tubes A.

K is the chimney, with which communicate three horizontal tines, L L L", situated one above another, each of these fines being furnished with a damper, m, which can be operated readily fiom the outside of the brick-work. Each of these horizontal fines communicates, through any desired number of openings, n, with the chamber containing the generator.

It is highly important, in boilers of this class, that the joints, where a union is efi'ected between vertical or inclined and horizontal. tubes, should be protected from the direct action of the fire. This end is effectually accomplished by embedding the lower end of the generator in the brick-work which serves as the foundation, and this is done without any material loss of heating-surface. It'is also important that the direction of the products of combustion from the chamber containing the generator should be changed, as circumstances may suggest. I

Thus, should it be found that the products of com.- bustion act too severely on the lower portion of the generator, the communication of the lowest horizontal flue L might be cut off by closing its damper, or the dampers of the whole of the fines might be so regulated that a uniform dissemination of the products of combustion throughout thechamber containing the generator might be obtained, and every por'tionof the tubes A forming the water-space ofthe boiler thus exposed to a uniform heat.

I wish it to be understood that I do not desire to confine myself to any specific number of rows of tubes A, or to any determined number of fines arranged one above another, as the size of the boiler must determine these points; but q I claim as my invention, and desire to secure by zontal pipes 13, and a steam-chest or'reservoir, E, sub- In testimony whereof, I have signed my name to stantially as described. this specification in the presence of two subscribing 2.
